OIL-CAN VENT.

Specification of Letters Patent.

Patented Sept. 18, 191 '7.

Application filed March 10, 1917. Serial No. 153,839.

To all whom it may concern:

Be it known that I, THOMAS F. DURNING, a citizen of the United States,residing at Newark, in the county of Essex .and State of New Jersey,have invented certain new and useful Improvements in Oil-Can Vents, ofwhich the following is a specification, reference being had therein tothe accompanying drawing.

This invention relates to improvements in oil can vents, beingespecially adapted for use in connection with oil cans for holdinglubricating and other oil, it being the present practice to provide novent for these cans so that in pouring the liquid it has been foundnecessary to puncture the top and thus render the can useless for asecond or subsequent filling.

It is therefore the object of this invention to provide a vent whichwill be securely held in place against accidental removal but which canbe readily removed when the liquid is being poured, thus permitting thecan to be refilled as many times as necessary and not necessitating the.loss of the can after the first filling.

In the accompanying drawings:

Figure 1 is a perspective view of an oil can.

Fig. 2 is a diagonal'cross section through the top thereof.

Fig. 3 is an enlarged detail View of the vent closure.

Referring to the drawings, the numeral 5 designates the can proper whichmay be of any conventional shape, here shown as a rectangular body, thetop being provided with the filling or pouring outlet 6. The ventopening 7 is formed by pressing the material of the top inwardly toprovide the lips 13 so that the closure 8 may be seated firmly thereinagainst accidental displacement.

This closure 8 is provided with a flexible connection 9 by means ofwhich the same is attached to the can to prevent its accidental loss.

The disk 10 thereof forms the outer closure to prevent the liquid fromoozing out when the vent is closed while the resilient holding member 11is composed of a single piece of metal having a plurality of tangs 1.2from the body and carried by the disk 10, the same exerting an outwardpressure so when in position as shown in Fig. 2, the gasket 14 will beheld tight upon the outer surface of the top of the can and the ventopening 7 closed.

From the foregoing description it is evident that with a vent device ofthis kind for oil cans, the can will have renewed life inasmuch as itwill not be destroyed by producing a vent opening as is the usual customand that with the closure the vent opening will be closed tightly sothat the oil will not leak out at this point.

What I claim as new is:

1. A sheet metal receptacle having a vent opening formed in the topthereof, the wall of said opening being tubular and convexed crosssectional longitudinally thereof, and a closure for the opening flexiblyconnected to the receptacle, said closure including a circular sealingmember, and a resilient member of lesser length than the wall of theopening for engaging the wall to frictionally hold the sealing member inclose contact with the outer face of the receptacle adjacent theopening.

2. A sheet metal receptacle having a vent opening formed in the topthereof, the wall of said opening being tubular and converted crosssectional longitudinally thereof, a closure for the opening flexiblyconnected to the receptacle, said closure including a circular sealingmember, a resilient semiglobular wall engaging member carried by thesealing member of the closure and of such length as to project slightlybelow the narrowest point of the opening, whereby the sealing member isheld in close contact with the outer face of the receptacle, and agasket interposed between the sealing member and the semi-globular wallengaging member for engaging the outer face of the receptacle.

In testimony whereof I affix my signature.

THOMAS F. BURNING.
